Chuck BKR6E NGK plugs into her (.8 gap) and it should fix it, if not look at your coil packs. Common skyline missfire problem.

Had that same problem definately spark plugs. try usings heat range 7 better plug as they run at a coller temp. helps with keeping knocks down

Sounds like detonation to me. Could be time for a new fuel pump and a tune up.

Could also be the spark blowing out at high boost that that will usally happen when boost comes on as aposed to at high revs.

Change and gap the plugs. If it still happend then its detonation which will kill a motor prety quick.

oh okay thanks alot for all your help but now i cant even test out my new spark plugs

cause my car wont even run =/

becuase after i came back from the mountins near home ( thank god) my car started losing

power. everthing slowly started dieing, and then everything shutdown.

i can jump start the car and let it run off the jumper battery but the moment i

take the leads off the car just cuts out.

PROBLEM AFTER PRBLEM =[
